Spreadsheet Overview and Basic Functions

Spreadsheet Overview

• Spreadsheets are electronic worksheets used for managing and manipulating data organized in rows and columns.
• VisiCalc (1979), Lotus 1-2-3 (1983), and Microsoft Excel (1987) are prominent spreadsheet programs.
• Common spreadsheet uses include personal budgeting, business profit/loss calculations, financial modeling, and stock analysis.

Spreadsheet History

• VisiCalc was used on Apple II computers.
• Lotus 1-2-3 ran on DOS-based IBM systems.
• Microsoft Excel and Apple Numbers were developed later.

Spreadsheet Topics

• Understanding Spreadsheets: Core concepts of spreadsheet operations.
• Logical Operators and Functions: Employ logical operators like AND, OR, NOT and functions like IF, for conditional calculations.
• Mathematical and Statistical Operators and Functions: Use mathematical operators and functions like SUM, AVERAGE, MAX, MIN, COUNT, etc. to analyze numerical data.
• Text Functions: Utilize functions such as CONCAT, LEFT, RIGHT, MID, FIND, SEARCH, etc., to manipulate text data.

Cell and Range Addresses

• Cell addresses use a letter-number format (e.g., A1, B2).
• Range addresses describe a group of cells (e.g., A1:C3, B5:B9).

Formulas

• Formulas use operators and functions to perform calculations.
• Formulas typically start with an equal sign (=).
• Constants (numbers or text) are used in calculations.

Relative Cell References

• Relative cell references adjust when copied.
• Copying a formula using a relative reference will adjust the cell addresses to the new location.

Absolute Cell References

• Absolute cell references do not change when copied.
• Using the dollar sign ($) in front of the cell address fixes the row and/or column of reference, thus maintaining it when copied to a different cell.

Mixed Cell References

• Mixed references combine absolute and relative references, keeping either the row or column fixed.

Range References

• Range references define groups of cells within a spreadsheet.
• A range reference can be used in formulas to reference the contents of multiple cells at once, saving effort.

Automatic Recalculation

• Spreadsheets automatically recalculate values when input data is modified.
• Data alterations result in automatic calculation updates in other cells linked via formulas.

Logical Operators and Functions

• Logical Operators: >, >=, <, <=, =, <> are symbols determining logical comparisons.
• Logical Functions: AND, OR, NOT and IF are frequently used with these to achieve specific calculations based on true or false results.

Mathematical and Statistical Functions

• Mathematical Operators: +, -, *, /, % are standard calculation operators within formulas.
• Mathematical Functions: Functions such as SUM, AVERAGE, MAX, MIN, COUNT, etc., perform various statistical analysis operations.

Text Functions

• These facilitate text manipulation within spreadsheets.
• Text manipulation functions allow extracting and concatenating text data from cells for desired formatting and usage in computations.

Additional Notes

• Spreadsheet programs offer various functions for different types of data analysis.
• These functions should be used correctly to perform exact computations.
• Functions utilize specific parameters for different operations of data.
